Revisiting the vCider SDN Solution Prior to Cisco Acquisition
Revisiting the vCider SDN Solution Prior to Cisco Acquisition : I never really got a chance to know what vCider brought to the menu of network industry disruption prior to their recent acquisition by Cisco.

Cisco Networkers Live CLUS or whatever we call it now SDN Predictions
I was emailing with my buddy Roy at SDN Central http://www.sdncentral.com/ about it would be fun to see a poll for people to guess what Cisco will do with their big SDN announcement. I jotted down four options that are all in the realm of possibility, or at least the same realm of if SDN makes sense and will adopt. Let’s say solar-system …
